Abstract
The present study determined the concentration of organochlorine pesticides (OCPs) in fish feed, cattle feed, poultry feed, fish, Poultry chicken meat, egg, Cow milk and beef and assessed the potential human health risks due to consumption of foods from animal sources. Gas Chromatography coupled with Mass Spectrometry (GC–MS/MS) was used to detect the presence of OCPs residues. Several OCPs residues including Aldrin, p’,p’-DDD, p’,p’-DDT and Endosulfan sulfate were detected in fish; Aldrin, p’,p’-DDE, Heptachlor, p’,p’-DDT and HCH were detected in poultry chicken meat; Aldrin, p’,p’-DDE and DDD were detected in egg; Aldrin, p’,p'DDE and p’,p’-DDT were detected in cow milk and Aldrin, p’,p’-DDE, p’,p’-DDT, Endrin and HCH were detected in beef. OCPs residues were detected within the range of EU/FAO's recommended maximum residue limits (MRLs). The Health risk index (HI) values of detected OCPs were ranged from 0.295914 to 0.834996; 0.00059628 to 0.09085834; 0.087882 to 0.090889; 0.05462 to 0.312114 and 0.008468 to 0.179828 for fish, Poultry chicken meat, egg, cow milk and beef respectively. The HI values of simultaneous exposure to different OCPs from the total food of animal origin (cow milk, beef, fish, chicken meat and egg) were 0.829889954, 0.825673025, 0.035987457, 0.0557969 and 0.179828343 for aldrin, Σ p,p-DDE, DDD and DDT, Heptachlor, HCH and Endrin respectively which are also below than 1. HI value of lower than 1 indicates no potential health risks while more than 1 HI value indicates potential health hazardous. This work provided information about the occurrence of OCPs traces in animal feed and animal derived food items and their impact on public health.
